For some reason I'm not able to get the modpack to work on Steam. Is there something that I'm missing. I've redownloaded the game through the Wargaming game center and the mod works there but I won't be able to use my Steam account which has all of my progress in it. At this point am I supposed to choose between restarting my progress on the game center version and be able to use mods, and Playing with my progress but without mods?
